Hunting is going out to kill animals. Animals, and some humans, hunt for food. Other humans do it for fun. Many places have rules that limit hunting. People were hunting since the time when people used stone and wooden tools. They used spears, and now people use guns and bows. Some people even kill the animals to make clothes, or to make their homes gorgeous, or even to sell them for money.
Hunting can be good by keeping animal populations from getting too high. Hunting too much, though, can kill off species of animals, also known as becoming extinct. Hunting once made the dodo, a bird, become extinct.
